2d1dd5943d soc/intel/common: Move update_mrc_cache after BS_DEV_ENUMERATE
This patch ensures that MRC cache data is already written
into SPI chip before SPI protected regions are getting locked
during BS_DEV_RESOURCES-BS_ON_EXIT.

This requirements are intended to support platform security
guideline where all required chipset registers are expected
to be in lock down stage before launching any 3rd party
code as in option rom etc.

coreboot has to change its execution order to meet those
requirements. Hence storing mrc cache data into SPI has
been moved right after pci enumeration is done, so that
SPI registers can be lock down before calling post pci
enumeration FSP NotifyPhase() API which is targeted to
be done in BS_DEV_ENABLE-BS_ON_ENTRY.

TEST=Ensure MRC training data is stored into SPI chip and power_
Resume autotest is passing.

581738642f Reinvent I2C ops
Do not use the global platform_i2c_transfer() function that can only be
implemented by a single driver. Instead, make a `struct device` aware
transfer() function the only interface function for I2C controller dri-
vers to implement.

To not force the slave device drivers to be implemented either above
generic I2C or specialized SMBus operations, we support SMBus control-
lers in the slave device interface too.

We start with four simple slave functions: i2c_readb(), i2c_writeb(),
i2c_readb_at() and i2c_writeb_at(). They are all compatible to respec-
tive SMBus functions. But we keep aliases because it would be weird to
force e.g. an I2C EEPROM driver to call smbus_read_byte().

dc1e6bc277 intel/common/block/fast_spi: Add config option to disable write status
Chrome OS systems rely on the write status register to enable/disable
flash write protection and disabling this opcode breaks the ability
to enable or disable write protection with flashrom.

Add a configure option for this feature that will disable the opcode
for Write Status commands unless CONFIG_CHROMEOS is enabled.

Tested to ensure that a default build without CONFIG_CHROMEOS has this
option enabled while a build with CONFIG_CHROMEOS does not.  Also
ensured that when this option is disabled (for Chrome OS) then flashrom
can be used with the --wp-enable and --wp-disable commands, depending
on the state of the external write protect pin.

029dfff30c i2c: Move to Linux like struct i2c_msg
Our current struct for I2C segments `i2c_seg` was close to being compa-
tible to the Linux version `i2c_msg`, close to being compatible to SMBus
and close to being readable (e.g. what was `chip` supposed to mean?) but
turned out to be hard to fix.

Instead of extending it in a backwards compatible way (and not touching
current controller drivers), replace it with a Linux source compatible
`struct i2c_msg` and patch all the drivers and users with Coccinelle.

The new `struct i2c_msg` should ease porting drivers from Linux and help
to write SMBus compatible controller drivers.

Beside integer type changes, the field `read` is replaced with a generic
field `flags` and `chip` is renamed to `slave`.

Patched with Coccinelle using the clumsy spatch below and some manual
changes:

* Nested struct initializers and one field access skipped by Coccinelle.
* Removed assumption in the code that I2C_M_RD is 1.
* In `i2c.h`, changed all occurences of `chip` to `slave`.

a8198eb9ad soc/intel/common/uart: Add support for enabling UART debug controller on resume
It has been observed on a number of platforms (baytrail, kaby lake)
that if serial console is not enabled in coreboot, but is enabled in
kernel (v4.4), then on resume kernel hangs. In order to fix this, add
support for enabling UART debug port controller on resume.

In order to decide whether UART debug port controller should be
enabled in ramstage, following things are checked in given order:
1. If coreboot has serial console enabled, there is no need to
re-initialize the controller.

2. This special action is taken only for UART debug port controller.

3. If boot is not S3 resume, then initialization is skipped.

4. Callback into SoC to check if it wants to initialize the
controller.

If all the above conditions are met, then UART debug port controller
is initialized and taken out of reset.

BUG=b:64030366
TEST=Verified with the entire patchset series that:
1. If coreboot does not have serial console enabled, but Linux kernel
has console enabled, then on resume, coreboot initializes UART debug
port controller.

2. If coreboot and Linux do not have serial console enabled, then
coreboot does not initialize UART debug port controller.

3. If coreboot has serial console enabled, there is no change in
behavior.

1. Create a new function uart_lpss_init which takes the UART LPSS
controller out of reset and initializes and enables clock.

2. Instead of passing in m/n clock divider values as parameters to
uart_common_init, introduce Kconfig variables so that uart_lpss_init
can use the values directly without having to query the SoC.

5. Use 'U' suffixes on the literals so we don't trip up compiler being

6. Use unsigned and fixed-width types for the reset mapping structure

01f9aa5e54 Consolidate reset API, add generic reset_prepare mechanism
There are many good reasons why we may want to run some sort of generic
callback before we're executing a reset. Unfortunateley, that is really
hard right now: code that wants to reset simply calls the hard_reset()
function (or one of its ill-differentiated cousins) which is directly
implemented by a myriad of different mainboards, northbridges, SoCs,
etc. More recent x86 SoCs have tried to solve the problem in their own
little corner of soc/intel/common, but it's really something that would
benefit all of coreboot.

This patch expands the concept onto all boards: hard_reset() and friends
get implemented in a generic location where they can run hooks before
calling the platform-specific implementation that is now called
do_hard_reset(). The existing Intel reset_prepare() gets generalized as
soc_reset_prepare() (and other hooks for arch, mainboard, etc. can now
easily be added later if necessary). We will also use this central point
to ensure all platforms flush their cache before reset, which is
generally useful for all cases where we're trying to persist information
in RAM across reboots (like the new persistent CBMEM console does).

Also remove cpu_reset() completely since it's not used anywhere and
doesn't seem very useful compared to the others.

89331cd4c8 soc/intel/common/block: Add Intel common FAST_SPI code
Create Intel Common FAST_SPI Controller code.

This code contains the code for SPI initialization which has
the following programming -

* Get BIOS Rom Region Size
* Enable SPIBAR
* Disable the BIOS write protect so write commands are allowed
* Enable SPI Prefetching and Caching.
* SPI Controller register offsets in the common header fast_spi.h
* Implement FAST_SPI read, write, erase APIs.

e4d7abc0d4 lib: provide clearer devicetree semantics
The devicetree data structures have been available in more than just
ramstage and romstage. In order to provide clearer and consistent
semantics two new macros are provided:

1. DEVTREE_EARLY which is true when !ENV_RAMSTAGE
2. DEVTREE_CONST as a replacment for ROMSTAGE_CONST

The ROMSTAGE_CONST attribute is used in the source code to mark
the devicetree data structures as const in early stages even though
it's not just romstage. Therefore, rename the attribute to
DEVTREE_CONST as that's the actual usage. The only place where the
usage was not devicetree related is console_loglevel, but the same
name was used for consistency. Any stage that is not ramstage has
the const C attribute applied when DEVTREE_CONST is used.

9d9a121fa0 soc/intel/common: provide default tis_plat_irq_status() implementation
On Intel platforms utilizing the CR50 TPM the interrupts are routed
to GPIOs connected to the GPE blocks. Therefore, provide a common
implementation for tis_plat_irq_status() to reduce code duplication.
This code could be further extended to not be added based on
MAINBOARD_HAS_TPM_CR50, but that's all that's using it for now.
